The kindergarten minibus with mixed-age children
Your 16-seat minibus has a driver plus 15 passenger seats. You must take 12 children and three staff on a kindergarten outing. The children are: four-year-old A (102 cm, 16 kg), six-year-old B (118 cm, 21 kg), eight-year-old C (132 cm, 30 kg), eleven-year-old D (148 cm, 38 kg), and eight more children aged 6–8 who are between 115 and 130 cm. The layout is: front passenger seat with an active airbag; second row three 3-point belts; third row three 3-point belts; fourth row four lap-only belts; rear row two 3-point belts. You have two forward-facing child seats with harness (9–18 kg), three booster cushions (15–36 kg) and one high-back booster (15–36 kg). Staff are adults. The lap-only seats are type-approved in the vehicle.
1. Which children can legally use which seats, and what is the main seating problem?
Read the worked answer
In Denmark, children under 135 cm must use an approved child restraint suitable for their height and weight. A, B, C and the eight 115–130 cm children are all under 135 cm, so 11 children need a child seat or booster. D at 148 cm can use the vehicle belt. A child seat or booster must not be used on a lap-only belt; it needs a 3-point belt or a proper ISOFIX/approved installation. The 3-point seats available are three in row two, three in row three and two in row five: eight seats. The front passenger seat also has a 3-point belt, but it has an active airbag, so it is not suitable for a rear-facing seat and is best avoided for a forward-facing child seat. That gives at most nine usable 3-point positions for 11 children who need restraints. The main problem is therefore not the total seat count but the belt type: you cannot lawfully or safely put the under-135 cm children in the four lap-only seats. One run cannot carry all 12 children with the restraints available.
2. How would you plan the trip to be legal and safe, including supervision?

Split the group into two runs or use a second vehicle with enough 3-point belts. On each run, put the youngest children in the harness seats, then allocate boosters to the taller children within the booster's weight range. D can use a 3-point belt and should not be placed in a lap-only seat if a 3-point seat is free. Adults may use the lap-only seats, but keep at least one staff member in the rear half of the vehicle to supervise and to operate the emergency exit. Do a headcount before moving off and after every stop, and assign each staff member named children. Do not put a child in the front seat with an active airbag unless the child seat and airbag combination is approved and the seat is moved fully back; the safest plan is to leave the front seat empty or use it for an adult. If the second run is used, the driver must still comply with driving hours and tachograph rules.
3. What checks on child seats and belts should be made before departure?
Read the worked answer
Check that each seat is approved and suitable for the child's weight and height, and that it is correctly fitted. The harness should be tight, with no bulky coats under it; the buckle should click and the belt should not be twisted. Booster cushions must route the lap belt across the hips, not the stomach, and the shoulder belt across the shoulder, not the neck. Do not use a booster on a lap-only belt. Check that the child seat is not resting against an active airbag and that the front seat is set back. Test every seat belt by pulling it sharply, check the buckles and the belt stalks, and make sure no seat is folded or obstructed. Finally, check the emergency exits and the first-aid kit, and brief the staff on what to do if a child undoes a belt during the journey.
